We do have a Performance Tuning Guide after all, and I'd like to add these instructions to that guide with additional links to the GMS sections in the HA Admin Guide. However, I need additional instructions on how to set this property. I tried doing:
asadmin> set configs.config.cluster1-config.group-management-service.org.shoal.cache.transmitter.max.batch.size=20
remote failure: No configuration found for configs.config.cluster1-config.group-management-service.org.shoal.cache.transmitter.max.batch
Command set failed.
As a starting point, I tried using the instructions in To Preconfigure Nondefault GMS Configuration Settings (http://download.oracle.com/docs/cd/E18930_01/html/821-2426/gjfnl.html#gkoac), but they didn't help.
Can you please provide additional information?
